feat(templates): fix unresponsive action dropdown for non-admin

Two changes that together restore the per-row Edit / Delete menu
for non-admin users:

- ``templateActions`` drops the blanket ``access: 'canSeeAdmin'``
  gate on every menu item. With the gate on, non-admin callers got
  an empty filtered menu, so clicking the "..." did nothing.

- The management page passes ``mine=true`` to the list API. The
  endpoint now drops Global rows for non-admin callers (rows they
  can't edit anyway), so the dropdown shows up only on rows the
  caller may manage. The GPU-instance create picker reuses the
  same API without ``mine``, keeping Global presets visible there.
